Hi,
Thank you for your kind words!
1. I’m afraid those stop words are only effective on the server side (on purpose). If you want, I can take a feature request and probably work out something for a future release.
2. You should try this feature. It depends on the browser too, but for most cases it should do the trick.
3. Can you share more details on this? I need to know exactly what the issue is. Error messages, how to replicate etc.. Let me know.
